The fittings seem to be on backwards. At least for my rig. Not to mention it's backwards in one of the promo pix. Way to go Neiko! Here's how I'm fixing mine. Female quick disconnect is fixed on my compressor, male quick disconnect -----> 1/4" FNPT ($6 for two) filter (the shiny drain valve should point back to the compressor, not the tool) *** Ideally the last piece would be a 1/4" FNPT to 1/8" BSPT (but I can't find one) 1/4" MNPT to 1/4" MNPT ($7.80 for four) 1/4" FNPT to 1/8" BSPT (running an airbrush, so I have to reduce down to this quirky size) **Q: I have a supply air line hanging from the ceiling and I connect to the bottom of it. Which way would the filter be hanging for best performance?** A: yes the valve should be at the bottom ! These filters appear to work both ways @! i have several and there don't appear to be any restriction on air flow either way i hook it up ! It should be fine both ways ! Might want to try it and see if it affects air flow for you ?I really don't care for it in the line and rather use it mounted on my paint gun ! I use the throw away ones for painting and this style for air tools with them mounted to the tool itself ! **Q: Can I put this after the regulator or will that drop pressure too much?** A: I recommend the bottom of you gun if possible. It is made to allow free flow. The pressure may drop a fraction of a pound. Not enough for anything... it pretty much just filters the moisture so you don't have water spots out your gun as you spray. I used it in line for an airbrush but would recommend an iwata if you are using it for that application **Q: Why are the reviews and questions for this model (30253A) the same as for model 30252A? There is clearly an error.** A: Check the manufacturer's specifications. It might be small dimension changes that do not affect the ability of the unit, i.e. length, diameter, etc. ## Customer Reviews ### ⭐⭐⭐⭐⭐ love the *by M***S on 28 July 2014* The airline water separator works as we had hoped. love the product ### ⭐⭐⭐⭐⭐ Es bueno y robusto *by C***R on 30 November 2023* Cumple con sus características lo recomiendo ### ⭐⭐⭐⭐⭐ Certainly traps water *by P***N on 27 August 2023* It certainly removes water, I got a good result with my spray job. ## Frequently Bought Together - NEIKO 30252A Water and Oil Separator for Air Line | 1/4" NPT Inlet and Outlet | 90 PSI | Air Compressor and Air Tool Accessory | Protect Lifespan of Pneumatic Tools | Water Moisture Filter Dryer - TCP Global 50 Pack of Ultra-Flow Blue Nylon Mesh Paint Strainers with 190 Micron Filter Tips - Premium Cone Screen Filters - 3M Accuspray Air Flow Control Valve, 16573 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/66353486-neiko-30252a-water-and-oil-separator-for-air-line-1](https://www.desertcart.tn/products/66353486-neiko-30252a-water-and-oil-separator-for-air-line-1) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-08*
